No. Apparently, nobody was as drunk/stupid as you. (Note use of lower case letters)

I have 22 month old twins, sometimes one will get an arm tangled in the blanket and cry for 5-10 seconds before going back to sleep, but it's enough to wake me up and I can never fall back asleep.

Also I lawn darted on Sunday and tore up my bad shoulder so I've been up at about 2-3am every day this week after the ibuprofen wears off... FML!

I don't understand the point of this build. Is it just spare parts you're piecing together?

I've done a XR100 motor in a KX80 roller, but at least it had a purpose.

Some people just do stuff just because they can. Personally I'd keep the original motor, but then again, this has been on CL for almost a year only a few miles from me. I'm starting to think with a dual sport light kit it might make a great white trash bar hopper!

I've built some pretty crazy stuff over the years, but that RD350 is just wrong!

Beer + boredom + well equipped shop = dangerous toys.

I just don't understand why the 1985 motor? Sorta like putting a pinto motor in a mustang, no?

Actually, the 2.3L Pinto motor was used for years in the Mustang.
Officially, that means Ford was stupid enough to do from the factory what most wouldn't do if they were drunk...

I'm pretty sure that my '88 Ranger had the same 2.3 Pinto motor. I had to rev the piss out of it in 4th to get to 65 on the freeway then shift to OD, if there was any headwind at all it would bog down below 60.

It was a great motor in a lot of ways. Easily buildable and virtually indestructible.

It was a crap motor, with terrible power potential due to the head design. Durable, yes, but a 04 rmz250 would be reliable if it only made 25hp.

Ford also used the boat anchor 2.3 in several front wheel drive vehicles including the stunning Tempo.

The first motor in the Pinto was a much better 2.0 design (crap, what does it mean that I know all this useless info about these lousy vehicles )?

Maybe it was the 2.0, but one of those ford motors was well liked from what I had observed "back in the day". Of course people do put crazy amounts of money into lost causes all day long, so maybe it was just kids in my area that seemed to like them. I've also observed kids putting a cam and all the Edelbrock bolt-ons onto a 305 and still have a POS that wouldn't beat a stock 350.

All this is extremely relevent to the this thread doncha think?

ok heres the deal. i know this motor is down on power , but thats not why im doing this build. im doing it because well i can. this build will cost me hardy nothing by useing my existing motor. if nothing else ive opened the door for those who have a 1986-1991 motor to know they have another option. if i want more power i can take the money i saved and mod this motor. with that being said i cut the front motor mounts off and the motor fell right in place. looks like i can use 2000 cr 250 head stays and my coil bolts right up.so far total spant 170.00 includes frame motor mounts and 2005 cfr 250 trees. thks everyone for your interest.

I get it Tomcat. If I had that motor and that roller, I'd put them together and ride.
I would not disassemble a perfectly good 1985 CR250 though. I'd rather sell the 2000 roller and put the money into the 1985. but maybe that's just me being sentimental and showing the love for old school smokers. Good luck with the project. I didn't imagine the engines were drastically different. Not enough to present a swapping challenge.

I agree, BIG difference! You can part out the 85 and get some good money or sell it whole. Either way, more money for the 2000.

Personally I have done worse, I put an XR200 motor in a CR125 frame to make the best handling XR200 in world...but the slowest bike ever. I think you are going to make a neat bike. And if you take the time to freshen up the 85 motor I think you will have a fast bike. My 86 CR250 pulls well of the bottom end and I always liked to motor.

Good luck,

Tdub13, are you racing WSP next weekend?

Hey Stooperbike, Are you the guy I met at the last vintage race? I'm going to miss racing next weekend. Looking to go practice at crow hill sometime soon during the week after though possibly. Want to join me on the '86? Hit me up.

Stooperbike you are so right about the bottom-end. my bike is stock but i love the power band. when im done with this conversion i plan on sending the top-end to eric gore im sure he can get some more power out of this motor. hey man you guys sound about my age but ill never tell LOL. one other thing i didnt take the bubble wrap off because im trying to protect the frame till im done with fad work almost done though. ill post more pics pretty soon from top to show how motor fits in frame and to get some addvise on head stays.

If you still have your XR 200/CR 125 hybrid; I believe XR's only still has go-fast parts for that XR 200 motor...granted I wouldn't go out racing a Service Honda CR 500 AF, but it'd get you down the trail a little faster...

The motor in the pic has HPP, the 85 CR still had ATAC I believe? Also, if it's from the bike missing the motor that's also in the pic, I'm pretty sure that's an 89 with those shrouds and USD forks. While we're on the topic... if your rear wheel bearings are still okay and you want to part with that back wheel... pm me : ) !
